utempter detection #3

Basic information

TDE version: all
Distribution: Slackware64
Hardware: amd64

Description

The utempter helper is not detected with cmake, as a result the utempter library isn't built in, even if WITH_UTEMPTER=ON has been requested as an option.

check for utempter ~ L600 in CMakeLists.txt

PATHS
        /usr/lib/${CMAKE_LIBRARY_ARCHITECTURE}/utempter
        /usr/lib/utempter
        /usr/libexec/utempter
        /usr/libexec
        /usr/sbin
        /usr/local/lib/${CMAKE_LIBRARY_ARCHITECTURE}/utempter
        /usr/local/lib/utempter
        /usr/local/libexec/utempter
        /usr/local/libexec
        /usr/local/sbin

Should be rewritten with either LIB_SUFFIX, ex:

/usr/lib${LIB_SUFFIX}/utempter

or with LIBDIR, ex:

/usr/${LIBDIR}/utempter

Then this can be passed as a cmake cmd like -DLIB_SUFFIX="64" or -DLIBDIR="lib64"

In TDESetupPaths.cmake in common cmake module, ${LIB_SUFFIX} is already in use, so it makes sense to use it also for utempter detection.
